Page 1. Panel
1. That's Carl Barks' Gyro
Gearloose in the upper left, DC's Killer Croc and Marvel's The Lizard
beneath him, DC's Ragman and Art Spiegelman's Maus in the center of the panel,
the Tazmanian Devil to the right, and Marvel's Scarlet Witch on the far right.
Paul Di Filippo (hereafter "PDF") notes that the duck woman with the Scarlet
Witch is Disney's Magica de Spell.

Panel 2. On the far left is DC's Hourman and Chronos. To the right
is DC's Solomon Grundy, wearing an "Aberzombie and Flesh" t-shirt. (A dual
pun, that, working on the fact that Grundy is a kind of zombie and the slam
"Aberzombie," referring to the vast numbers of high school & college students
who all wear Abercrombie & Fitch clothes and so all look alike). In the
center of the panel is Dennis the Menace, with what PDF says is "Chris Ware's
Jimmy Corrigan, in elderly mode." PDF notes that to the right is Marvel's
Kang the Conqueror and DC's Time Trapper.

I don't know how the two characters on the far right of the panel are.

Panel 3. On the far left are Kang and the Time Trapper. Sitting beneath
the tree are what PDF says are "the three card-playing bats from "Pogo"...down
for a game." To their right are DC's Joker and Groucho Marx. Staring at the
tree is Dik Browne's Hagar the
Horrible. Next to Hagar is DC's Phantom Lady with what PDF says is Vampirella.
Next to Phantom Lady and Vampirella are Marvel's Stick and Elektra. I don't
know who the two characters behind them are.

To the right are Marvel's Dead Girl and what PDF says are Marvel's Gwen
Stacy and Karen Page. On the far right are Hourman and Chronos.

Panel 4. On the far left are Vampirella and Phantom Lady. Next to
them are the three bats from "Pogo." Next to them are Marvel's Tigra nad DC's
Catwoman. In the center of the panel are DC's Amanda Waller and what PDF
says is Henry Gyrich (not Jasper Sitwell, as I guessed). I don't know who
the two characters next to them are.

On the right are what PDF says are Marvel's Mystique and DC's Clayface.
On the right are Dick Tracy and Fearless Fosdick.

On the left is Marvel's Golden Age Destroyer.
I don't know who the character is to the left of the Destroyer's head, or
the character beneath his armpit.

The character in blue chain mail and an orange vest is, I think, a miscolored
Stalker. Next to him is
Marvel's Valkyrie. Next to her is DC's Abel (from House of Secrets
and later Sandman). Above him is...I don't know, nor the male character
with the "K" on his chest. Next to him is, possibly, DC's Black Canary. Next
to her is DC's Ultra Boy.

I don't know who the woman on all fours is, or the man yelling "Get away
from me!!"--possibly the Golden Age Catman? The woman on the far right is
DC's Cinnamon.

Panel 2. That is DC's Johnny Quick, from the Crime Syndicate of America.

Panel 3. I can't place either of the heroes in this panel (upper left,
lower right).

Panel 4. The scene on the Subliminal Kid's facescreen is the famous
scene from Batman's origin
in Detective #33. (Oh, wait, that's not the right origin. I couldn't
find an image online of the true origin).

Page 4. Panel 1. Apart from
DC's Northwind in the lower left, I can't identify any of the characters
in this panel.

Panel 2. Or this one. (Not doing too well this time around, I'm afraid).

Panel 3. I don't know who the woman is with the cape. Is that Bill
Willingham's Chrysalis next to her?

Page 8. Panel 1. Geoff
Rose points out that the computers are "O-Macs, a pun on the DC Infinite
Crisis plot point Brother Eye and the real world I-Mac."

Panel 4. That's Underdog in the lower left. I can't identify the cat-and-mouse
trio in lower center, or the boy with them. Presumably the cape-wearing dog
is Superman's companion Krypto. Next to Krypto is an altered Red Sonja.
